In a situation like that, users have no means of resisting egregious terms, and no you cannot pull up stuff like "if you don't like it, don't buy it". As I wrote, the users are uncoordinated, and would take a huge effort to coordinate. Boycotting services rarely works (if ever). So what we end up with is that legal teams employed by firms optimize to shove as much bullshit into ToS as they can, the users grind their teeth and bear the bullshit, and get shittier service. Nobody really wins, because I'd argue the marginal gain for the company is minimal at best from this.
The government is not there just to enforce laws, but also to legislate such that the scales are balanced. Otherwise we may as well live in a dictatorship.
